That was the ending? if their is more episodes it would explain that Aoba and Hina are the once that created the Coupling System in the past timeline and their still alive as an old grandma and grandpa in the future timeline and the Captain is their son or grandson or close to that since from the beginning that Captain is too accepting like he knows everything that is going to happen or knew Aoba and Hina if you ask me

A crap! It’s a shit! There we go again with the time loop,man this series is killing me! Youve got threesome, hina is being semi-rape and her boyfriend says he understand? WTF! Bizon’s gonna destroy a planet because he got NTR’d? And. And for the love of god i will say it again a TIME LOOP? to hell with that! The writers could just have end the story with a single movie and stop Elvira from blabering senseless things ALONE! done for good and scores 0.5/10
